are people living in Delhi really rude?

I live in Kashmir and we had this newcomer in our school from delhi.

Bhai ussai xyada gumandi, lalchi, pagal, spoiled, phasool, arrogant bacha mainai apni zindagi mai kabi nahi dekha hai, aur yai baat around 2019 ki hai, we were in 9th that year.

I know sarai log aesai nahi hongai obviously, but whenever mai delhi sunta hu mujai wo banda yaad ajata hai aur uski wo ajeeb personality, uska nature project hota hai delhi walo par, and I genuinely hate this. I hope tum log burai nahi ho.

But is this true?

edit: kuch log trigger kyu horahai hai? mai genuinely puchraha tha ki kyah yai sach hai ki nahi, but now I think yai true hai , tum log bohot rude ho even in the comments.

edit 2: initially bohot negative comments ayai isiliyai edit 1 aesa hai, but I think log bohot achai hai delhi mai but rude bi hai kuch, jo chalta hai.
